Thus this camera has a potential of developing the new reagents for molecular imaging. Until now we have carried out several imaging reagent studies such as : (1) F-18-FDG (511keV) and I-131-MIBG (364keV) for double clinical tracer imaging, (2) Zn-65(1116keV),Mn-54, Fe-59 in mouse for high energy gamma emitting RI imaging. In addition, ETCC can image continuum spectral gamma-rays by removing background particle using dE/dx of the track. ETCC has a potential of real-time monitoring of the Bragg peak location by detecting prompt gammas. We successfully obtained the images of both 511keV and continuum high energy gamma rays (800-2000keV) from the water target irradiated by 140MeV proton (Kurosawa, Cur. Apl. Phys, 12 (2012), pp. 364). In 2013 we have completed a 30cm cube ETCC to catch gamma-rays, of which tracking efficiency was improved with 10 times. It enables to select the Compton event contained in TPC using only the energy loss rate of the track with distinguishing it from all backgrounds. Eventually its sensitivity is improved by a factor of 100. A similar imaging test for prompt gammas using 140MeV proton beam was recently carried out, of which intensity was increased more 10 times than previous experiment. Here I present new performance of the improved ETCC and the results of the beam test.

There is 3.3 sigma discrepancy between the SM prediction and measured value. Muon’s electric dipole moment (EDM) limit is 10^-19 e・cm. The muon g-2/EDM at J-PARC (E34), aims to reach a sensitivity of 0.1 ppm, and try to measure EDM down to 10^-21 e・cm sensitivity. In this experiment, we accelerate muon to the 300 MeV/c, storage in the 3 T precise magnetic fields and reconstruct a track of muon decay positron by highly-segmented positron tracking detector. We use silicon strip sensor for the tracker because the tracker requires high rate capability, high stability against a large rate change, good operation in a high magnetic field, and good position resolution. The sensor specification is optimized by considering rate capability, and the sensor misalignment involves EDM sensitivity. We optimized sensor specification and estimated the requirement of accuracy of the alignment by using the simulation. Based on the specifications, we produced two types new test sensors. We evaluated the performance of test sensor, and estimated signal to noise ratio.

The DWL adopting double-edge technique of Fabry-Perot etalon requires outgoing laser frequency to fall on the abrupt linear region of the transmittance curve of F-P etalon. Vibration and temperature variation would cause frequency shift, which will further induce laser frequency to fall outside the linear region. While the precision and sensitivity of DWL greatly lowered, a locking channel is hereby designed for shift detection. According to the shift, the position of transmittance curve can be modulated, which guarantees the frequency falling on the linear region. An approach of detecting the frequency shift is to measure amplitude variation by Photomultiplier Tube (PMT). The output signal is periodic, with 50Hz in frequency, only 20ns-width and sharp edges. Consequently, it is difficult to measure amplitude of such a narrow pulse signal under relatively low sampling rate. To reduce the error caused by low sampling rate, the measurement of the pulse area is made to instead of pulse amplitude. Statistical methods are also applied for further accuracy and improving stability. A data acquisition system including circuit and a specific software is designed. The system includes external trigger, data acquisition and processing. Controlling system sends trigger parameters and acquisition commands via software. Tests using splitters have been carried out. The ratio results indicate consistent between the data acquisition system and commercial oscilloscope. The results with relative error of 0.80% also meet the locking requirements.

By measuring the track of an electron, ETCC measures the direction of gamma-rays as a small arc, which provides a good background rejection using the kinematical test and energy loss rate of the track (particle identification), and clear imaging. Already we revealed its strong background rejection ability by the balloon experiment (a 10cm-cube ETCC: SMILE-I) in 2006, where 98% background events were removed. In 2013 we completed a 30cm cube ETCC to catch gamma-rays from Crab in next SMILE-II balloon experiment with >5shigma for several hours. The tracking efficiency was improved with 10 times, which enables to select the Compton event in TPC using only the energy loss rate of the track with distinguishing it from all backgrounds. Thus, we can extract the maximum detection efficiency expected by the simulation. Also SPD angle provides a several times better contract in image than conventional Compton method. Then, SMILE-II would provide a 5times better sensitivity than COMPTEL with the use of 3atm CF4 gas, and 40cm-cube ETCCs onboard satellite is expected to reach near 10-12 ergcm-2s-1. To verify this performance, SMILE-II was irradiated by secondary gammas and neutron from water target using 140MeV proton beam, and measured the clear image of a weak source under 10times stronger radiation than that in the balloon altitude. Here we will present the detail of the SMIEL-II performance including this beam test.

This MCP-PMT has high photon detection efficiency which results from using transmission photocathode and reflection photocathode simultaneously, and the total quantum efficiency reaches approximately 30%. Good design of focusing electrode and appropriate distribution of voltage can ensure 95% photoelectrons entering the surface of MCP. The electron multiplication system consists of 4 MCPs that each of the two pieces of MCP is a component, by optimizing the voltages of each MCP and the gaps between MCPs, the gain obtained is greater than 107 and the peak to valley ratio of single photoelectron is about 2. For anode optimization, we design two kinds of configuration to reduce signal ringing, the one is metal mesh and plate, the other is micro-strip line. Finally, by using signal cable which impedance matches the anode, we obtain very single photoelectron signal.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: YUREVICH, Vladimir Submitted on: 31 January 2014 06:29 Title: Modular Detector with Picosecond Time Resolution Abstract content Nowadays the TOF measurement with picosecond time resolution is important feature in high-energy physics experiments and the detectors solving this task are important part of experimental setups. The initial point of our activity in this direction was a proposal of Fast Forward Detector (FFD) for MPD/NICA project [1]. The detector concept and results obtained with the first version of detector modules were published in [2]. Another considerable application is developing a modular array for BMN project [3]. Both these cases were studied by MC simulation and some the results are presented here. Application in experiments with rather low energy of heavy ions, sNN1/2 ~ a few GeV, is the most difficult case because in such collisions the produced particles have the smallest multiplicity and mostly their velocities β are essentially less of 1. The examples are novel experiments CBM at SIS-100, BMN at Nuclotron, and MPD/NICA which are in preparation stage. In this report the experience in developing and testing modules for detector arrays with picosecond time resolution based on registration of Cherenkov radiation induced by relativistic charged particles and high-energy photons is described. The important point for ps-timing and operation in magnetic field is application of MCP-PMTs XP85012/A1-Q from Photonis. The main idea of the detector concept is registration of ultrarelativistic charged particles and high-energy photons by conversion to electrons in lead layer in front of quartz radiator. The total active area of the module is 59 × 59 mm with zero dead space (only module housing defines the dead area). It is very important point because it allows designing detector arrays without any dead space. The module has four independent cells/channels. The quartz radiator has 15-mm thickness and it is segmented into four bars. The radiator is optically coupled with MCP-PMT which has 8 × 8 anode pads transformed into 2 × 2 cells by merging 4 × 4 pads of each cell into a single channel. The FEE is carried out amplification and formation of output analog and LVDS signals. The performance of detector modules and modular arrays proposed for start signal generation in TOF measurements and triggering Au + Au collisions in MPD/NICA and BMN was studied by MC simulation and in tests with GeV single-charged ions of Nuclotron beam and cosmic rays. In the experimental tests three different types of readout electronics were used: (i) measurement of time and amplitude with TAC and ADC, (ii) determination of time and pulse width for LVDS signals, and (iii) analysis of pulse shape by digitizing with 200-ps/bin time scale. For single-charged particles with β ≈ 1 producing about 1800 Cherenkov photons in quartz, the module channel generated the pulses with pulse height of ~ 300 mV, rise time of 1.2 ns, pulse width of 5 ns at noise level of a few mV. The time resolution obtained in the measurements with two modules is ~ 30 ps (sigma) per module cell. It means that one may hope to get an excellent time resolution better than 10 ps in a real experiment where registration of a large number of charged particles and photons by modular array occurs in single events. 1.

It is expected to reach an order of magnitude better sensitivity than has been achieved so far by the best experiments in the field. The technical challenges of commissioning a payload of this size have led to the development of 1.4 kg germanium detectors (100 mm diameter, 33 mm thick), which are 2.3 times larger than those presently in use in the SuperCDMS experiment at Soudan. The first results from testing of a prototype detector with interleaved phonon and charge channels are presented. The test results are promising for the use of these detectors in the next phase of SuperCDMS. Summary Primary Authors: Dr. CHAGANI, H.

However a key problem of low count rates need to be tackled. A noval geometry and scintillator architectures with the AMOC spectrometer is designed to promote the spectrometer count rates. A well-shape BaF2 scintillator is employed to detect the 1.28MeV gamma photon emmitted while the generation of a positron, which improves the cross section by about three times. By placing the HPGE detector behind the photomultiplier tube in the line, HPGE detectecor can still capture the 0.511MeV gamma photon emmitted while the annihilation of a positron.A new hard trigger system is designed and utilized to reduce the dead time. The spectrometer with high efficiency is on debugging for better performance.
